worked perfect to improve the throttle progression of my MSD Atomic 2. with stock linkage it was nothing....then too much and chirp the tires! this helped smooth it out from a stop. I set it up where the secondaries come it at 20 primary throttle position. The base of this unit and the software is the same as the holley sniper. You will need to go into the software and adjust for progressive linkage.

This little jewel should have come in the box with my Holley sniper EFI. After I installed this baby I had to flash my Sniper firmware to work with the the new. My secondary barrels were opening exactly the same amount as my primary barrels making my take offs sudden and sketchy. Now my secondary barrels wait till I use 40 throttle. Very easy, tons of google articles on how to.
